exchangers which are more particularly used in connection with the gas engines of automobiles or other power installations for the purpose of cooling the water of such engines by passing,

the same through a plurality of water channels which are interspersed by a plurality of air passages, whereby the air during its movement through these passagescarries away heat from the water. Heretofore cooling units or cores for this purpose have usually been made from sheet metal,

such as copper or an alloy of the same, which material usually consisted of a large number of separately formed pieces assembled to produce a cellulous structure and connected with each other by means of soldering so as to render the joints between the several members water-tight. This construction is very costly on account of the large number of separate operations necessary for shaping and assembling the several parts and also the large amount of solder which is required for connecting the several pieces of each cooling unit or core and rendering the joints between the same leakproof.

It is the object of this invention to provide a cellular, cooling unit or core for radiators of this character in which the body in the preferred construction is made in one piece of material.

In the accompanying drawing:

Fig. 1 is a fragmentary perspective view showing the body of a cooling unit or core in which of reference indicate like parts in the several figures of the drawing:

In the construction shown in the drawing a radiator body preferably of aluminum is provided with comparatively thick upright webs 45, each of which contains an upright water passage 46 which is closed on one side by an integral closure 41 while the other end of each of these water channels extends to the opposite side of the'radiator body, as shown at, and theseveral wide 1938, Serial No. 224,592

upright webs are connected with each other by comparatively thin webs 49 which form the upper and lower walls of the air passages or tubes but do not contain any horizontal water passages. In this case those ends of the water channels which extend to one side of the radiator body are closed by aplurality of filling closures 50 of aluminum or the like having the form of strips or bars which are fitted into these water channels. These filling closures are constructed as a unit in the form of an open-work grid or frame as shown in Fig. 1 and may be connected with the body of the radiator in any suitable manner Each closure 50 is provided with flanges 52 which overlap the respective ends of the water channels 46 which extend to the side of the radiator body, as shown in Fig. 2. If desired a gasket or packing 53 of rubber, cork or similar material, maybe clamped between the flanges 52 of the closure bars 5|] and the adjacent ends of the webs containing the water channels so as to produce a water-tight joint, as shown in Fig.2. Thegrid forming the closure bars 5| is so constructed as to form narrowhorizontal covering bars 54 which are of the same width as the narrow horizontal webs 49 and extend over the same and the several gaskets 53 are connected by short gasket sections 55 which are arrangedbetween the cover bars 54 and the respective edgesof the narrow webs 49. The gaskets 53 and 55 are preferably constructed in one piece in the form of a grid to correspond with the grid-like form of the closure bars 50 and the covering bars 54 thereby producing a finished appearance of the cooling unit as a whole.

It will be noted that this invention permits the core or body of this cooling unit to be made of the same metal or similar metals so that the completed structure consists virtually of a single homogeneous mass which expandsand contracts uniformly and thus avoids strains which would be liable to crack the metal and cause leakage.

As a whole this core or cooling unit can be produced expeditiously by the use of relatively unskilled labor and thus reduce cost and the same i is not liable to injury due to vibration while in use thereby reducing the up-keep of the. radiator.

I claim as my invention; 1. A cellular core for radiators comprising an integral body provided with a plurality of rows of air passages and a plurality of water channels which alternate with said rows of air passages and each of said water channels being closed at one of its longitudinal sides by a wall which constitutes an integral part of said body, and closures which cover the opposite longitudinal sides of said water channels and each of which closures constitutes a part separate from said body and is secured thereto and each of said closures having a strip which is arranged within one of said water channels and flanges projecting laterally from said strip and overlapping the adjacent outer side of said body.

2. A cellular core for radiators comprising an integral body provided with a plurality of rows of air passages and a plurality ofwater channels which alternate with said rows of air passages and each of said water channels being closed at i one of its longitudinal sides by a wall which constitutes an integral part of said body, closures which cover the opposite longitudinal sides of ing a strip which is arranged within one of said a water channels and flanges projecting laterally from said strip and overlapping the adjacent outer side of said body, and a gasket interposed be- 10 tween said flanges and said body.
